Middle schoolers analyze an animal's life cycle and behaviors, and examine what animals need to stay alive and reproduce. They develop theories and hypotheses about the reasons for migrations, using the Journey North online project.

Young scholars share hypotheses about the variables needed to produce a collision between two moving objects. They simulate the impact of a moving object on an object that creates a spray of debris, and simulate a NASA Deep Impact study.

Learners formulate hypothesis based upon data gathered by examining possible crosses of spiderworts using Punnett squares. They present explanations for physiological adaptations of spiderworts that resulted from interactions within the...

Students voluntarily participate in a sensory test and examine hypothesis testing and statistical significance. They use low-fat and original Oero cookies for this experiment.

High schoolers explain the different heat transfer mechanisms and how they influence the building envelope. They develop ways in which the building envelope can be improved and test hypotheses about building envelope designs.

Students demonstrate how epidemiological investigations of outbreaks are performed. They illustrate the principles of hypothesis formation and testing by epidemiologic study in the setting of an acute foodborne disease outbreak.

Students witness a flood demonstration, offering hypotheses and observations throughout the demonstration. Students discuss flood prevention techniques and examine the impact of the devastating flood and mudslides in Venezuela. In small...

Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...

Young scholars utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether...

Students investigate evolution in its most fundamental form: the observation of living organisms. By comparing variations that exist among living animals, students formulate their own hypotheses and conclusions about the evolution of...

Fifth graders record at least four hypotheses concerning what happens when they drop an egg from a high spot. They record at least five observations or supporting ideas about the egg drop. Students test gravity by dropping an egg from a...

Students hypothesize about why various samples of coal have different characteristics. Pupils use information that they found during Internet searches to ascertain the validity of their hypotheses and verify the "story" of coal. ...

In this control and experimental variables worksheet, students read about the variables in an experiment and practice identifying each in 2 experiments. Students analyze the data in an experiment, identify the hypothesis and the...

In this density worksheet, students investigate what will happen when various liquids with different densities are put into the same container. They hypothesis and make observations. Students answer 4 questions about their investigation...

In this weathering worksheet, students investigate the effects of water and acid on limestone. They form a hypothesis for both and experiment to find the results.

In this motion worksheet, students design an experiment to investigate motion. They form a question, they develop a hypothesis, they design an experiment and then answer 4 questions about their experiment.

In this solar storms worksheet, students use an on line source to read newspaper stories about scientific theories and hypothesis related to space weather phenomena. Students answer 7 questions about past solar storms and compare ideas...

In this nature of science activity, learners identify four statements as "pure" or "applied" science and they read a short story about an experiment performed by a boy. They identify various components of the experiment...

Students create flubber glaciers. For this glacier dynamics lesson, students experiment factors that may affect glacier speed. Factors include slope, ice temperature, and basal conditions. Students develop hypothesis, conduct experiment,...

In this geometry instructional activity, students read given sentences and identify the hypothesis and the conclusion of the conditional statements. There are 21 questions.

Students predict the safest seashore substrate for animals. In this animal habitat experiment, students predict, test their hypothesis, and record data about how wave shocks affect animals living on either sand, gravel or rock. 

Students analyze water quality data from real data. In this environmental science lesson, students examine how salinity and dissolved oxygen affect the living organisms in the estuary. They interpret graphs to support or disprove a...

Students research and formulate a hypothesis for research to correlate changing safety regulations in regards to personal and environmental safety polices for storage, handling and disposal of chemicals, risk involved in hazardous...

Learners create and test a hypothesis about cell division. After observation of Frog Egg cell division, students write obervations and refine process and hypothesis. The use of scientific method, group work and inquiry are fostered by...
